@pbmorrison-2 An electrolock is an armored cable housing that runs from the back of the ignition switch to the coil. They changed in appearance over the years but all served the same function, a deterrence to hot wiring and stealing a car. The image below shows the one on my old 38. A 31 would be different but I don't know what the specific differences would be (usually in how it connects to the coil).

@tiny in comparing your photo to my, looks like the Electrolock was replaced.  Thanks

The 31 electrolock armored cable would have gone from the switch to the distributor with a regular coil mounted on the firewall. Yours has been replaced. 

@david-dunton Thank you David. I've removed my incorrect post to not muddy the water. Do you have a picture of the correct set-up?

Here is a pic of the coil and you can see the armored cable running through the firewall. The other pic shows it at the distributor. I put a piece of split heaer hose around the cable to keep from accidentally grounding it on the starter cable lug.
